Centos Linux 5.1

Heartbeat v2

 

I have a cluster resource that is an IP address in a different subnet
than the real IP on the nodes.

 

When the cluster IP is added to a node I need to modify the routing
table so the default gateway or 0.0.0.0/0 route becomes an IP in the
cluster IP address subnet so that packets from the active node can be
sourced from the cluster IP address.

 

Is there a way to manage routes as a heartbeat resource, or is some type
of script required?

 

The route cannot be added without the cluster IP being active because
the gateway would be unreachable.

 

Example?

 

Thank you!
